To all whom it may concern:

7 Be it known that I, THOMAS A. DE VIL- BISS, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Atomizer; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

y invention relates to atomizers; and and efiicient instrument of this class, the. liquid and air-tubes of which are adjustable to enable the laterally-disposed discharge ends thereof to be shifted to direct their discharge in a multiplicity of directions, as the nature of the use or the parts to be sprayed may require.

e operation, construction and arrangement of the parts of the invention are fully described in the following specification, and while in its broader aspect it is susceptible of embodiment in numerous forms, two referred forms of the same are illustrate in the accompanying drawings, in which,-

one form of the invention with a the same in vertical section, and similar vlew of another form of mbodym ortion ig. 2 is a he same.

Referring to Fig. 1 of the drawings, 1 esignates the liquid receptacle, the neck of hich is closed by the head 2, which may e threaded within a ferrule 3 or secured to 5, which is ead and extends'down into he rece tacle to near the bottom thereof, nd wit a channel 6, which serves to open ommunication between the atmosphere and The channel 41 has its up eror outer end orizontally an led with t e extreme end I ereof enlarge to form a seat or bearin r the inner end of the liquid tube 7, whicfi be is attached by. bands 8,0! in any other itable manner, to the Specification of Letters Patent.

9, said tubes communicating at their outerends with a common spray head or nozzle 10, which is pivotally shiftable relative tiiereto, as is common in instruments of this c ass.

The inner end of the air-tube 9 passes over or at the side of the head 2 and terminates in a laterally offset enlargement 11 through which the member 12 threads. ber has its inner end projected beyond such enlargement and pivotally seating, in axial alinement with the inner end of the liquidtube 7, in the .enlarged outer end of a channel 13, which is providedlim the head 2 in opposition to the angled upper end of the channel 4 and opens laterally into the channel 6, thus combining with the inner end of the tube 7 to form trunnions for pivotally supporting the tubes 7 and 9 relative to the head.

The outer end of the member 12 is adapted to form the nipple to which the usual air sup ly tube "(not showm) attaches, and has its' ore communicatin with the channel of This memthe tube 9 through the passages 15-and 16 in said nipple and the en tively, and with the channel 13 in the head 2 through the fine or restricted passage 17 rovided axially in the inner end portion 0 the nipple, as shown. The outer portion of the member 12 shoulders against the outer face Figure l is a side elevation of an atomizer of the enlargement 11 to form a close joint therewith, and the inner end of such member seats within the outer end of the channel 13 with sufficient force in'opposition to the inner end of the tube 7 to frictionally resist a free pivotal movement of the tubes 7-9 and hold them in any position of adjustment relative to the head 2. It is apparent with this construction that the major portion of the fluid which passes through the nipple 12 under pressure enters the tube 9 and in discharging from the spray-head 10 creates a suction argement 11, respec through the liquid-tube 7, channel 4' and tube 5,-whereby to draw liquid from the receptacle 1 and discharge it from the sprayhead in vaporized form, tion of the pressure fluidis forced into the receptacle through the fine passage 17 in the member '12 and the channels 13 and The principal purpose of the communication between the source of fluid pressure and the receptacle is to facilitate what is commonly termed a fiooding 'of the spray parts,

which may be accomplished. by placing the while a small por-- thumb over the outer end of the air-channel augment the discharge occasioned by the 'ch'anne tends aroun suction created in the spray-head and eifect a consequent greater flow of liquid through the discharge tubes.

In the modificationshown in Fig. 2, a desi ates the receptacle, and b the head, which 0 oses the neck of the receptacle and carries the spray parts, said head having the air-, channel 0 and the liquid channel 0? therethrough, which latter communicates with the interior of the receptacle through a tube e. In this instance the air and liquld tubes 7, g are concentrically arranged in advance of the head I) with an annular space provided between them and with their outer ends curved laterally and provided with a spray-head h.

The outer tube f has its inner end attached to the enlar ed end a of a yoke j, which ex- 5 the head band has an enlargement is at its rear end throu h which a mpple Zis threaded or otherwise suitably secured. The nipple Z has its bore in communication with the annular assage between the tubes f and 9 through a c annel min said oke, as shown. The inner end of the nipple projects through the enlargement is of the yoke and has a pivot bearing in one side of the head b, in a similar manner to the form above described, and such nipple end has a restricted passage 11. therethrough which combines with a passage 0 in the head to open communication between the major portion of the nipple bore and the channel 0. The inner end of the liquid tube 9 projects through the enlargement z of the yoke 7' and has a bearin in the enlarged outer end of the d in axial alinement with the nipple l the inner end thrust of which it opposes.

It is a parent with both forms of the invention t at the liquid and air tubes may be easily and quickly disen aged from the head carrying the same for t e purpose of cleaning, or otherwise, by simply unscrewin the nipple member to release its inner end rom en gement with such head.

wish it understood that my invention is not limited to any specific construction or arrangement of the parts, except in so far as such limitations are specified in the claims.
